AN EXPERIMENTAL STUDY ON THE PERFORMANCE BEHAVIOUR OF INSTRUMENTED PROTOTYPE REINFORCED EARTH EMBANKMENT. REINFORCED SOIL AND GEOTEXTILES, PROCEEDINGS OF THE GEOTEXTILES CONFERENCE HELD AT THE INDIAN INSTITUTE OF TECHNOLOGY, BOMBAY, INDIA, DECEMBER 8-9, 1988

This paper presents a study of the performance behaviour of a prototype reinforced earth embankment during and after construction. The structure consisted of an embankment 4.2 m high with vertical faces and 10.5 m wide, and a 60 m long approach ramp with a slope of 1 in 15 on one side. Skin elements of galvanised iron (GI) and roller compacted concrete (RCC) were used on the approach ramp, and aluminium and GI strips were used in the embankment itself. Conclusions show that during construction the lateral displacement of the wall was found to increase above a height of 2.25 m, in the absence of temporary supports. The increase in deformation under the maximum surcharge load was only 0.5% of the height of the embankment. The lateral pressures on the skin elements at the end of construction were about 1.2-1.5 times the predicted volume, but under applied loads, recorded pressures were 1-10 times the theoretical value.
